Subject: [PATCH v2 8/8] remoteproc: qcom: Introduce panic handler for PAS and ADSP
Date: Thu, 26 Dec 2019 21:32:15 -0800
Message-ID: <20191227053215.423811-9-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20191227053215.423811-1-bjorn.andersson@linaro.org>

Make the PAS and ADSP/CDSP remoteproc drivers implement the panic
handler that will invoke a stop to prepare the remoteprocs for post
mortem debugging.
